Jen,
Here is our favorite B&B in Ireland. http://www.bedandbreakfastireland.net/Kerry_Duinin_Hse.htm
It's located just a km from Dingle on the Connor Pass Road. The proprietors, Pat and Ann, are great. My wife and I have stayed there twice. We discovered it in 1999 on our first trip and stayed there again in 2005. The breakfasts are outstanding. They actually have a printed menu, which is rare in b&b's. If you like hot cereal, I highly recommend the porridge served with Bailey's Irish Cream. And if you are a coffee person, they offer French pressed coffee. Most places only have instant (Nescafe).
You will not have a difficult time getting a b&b, they seem to be everywhere.
We found the Irish people very wonderful and helpful....sometimes a little difficult to understand unless they speak slowly, but all in all very great people.
As for sightseeing, Rick's books & videos are a great start and you have plenty of time to plan. A few of our favorites are Trinity College (Book of Kells), Glendalough, Clonmacnoise, Cliffs of Moher, Beara Peninsula, any/all of the castles.
Driving alone will be a challenge. (A navigator/second driver is a great relief) If possible, get a GPS. Driving the backroads (usually how you get to any of the sites) is sloooowwww. Yes, they are narrow, too. Sometimes you will encounter either hedge rows, rockwalls or a combination of both, next to the pavement. You will have close encounters with lorries and fast moving residents.
Just take your time and you will have a great experience. I will research our info and send a PM.
